YES.

Although 8" "emulation" sometimes cheats and uses 80.
And some users with drives without a physical stop tried to squeeze a few 
more tracks  (and 41,42 on 360K)
The inability to read those "extra" tracks on a different drive didn't 
show up until the disk was nearly full (inner tracks are normally last 
allocated)

SA400 was 35 track (TRS80, and SA390 Apple)
Q: how many tracks are the HP formats?
